I-Vitamin B7 (i-Vitamin H/D-Biotin) I-CAS: 58-85-5 Umhlinzeki Womkhiqizi

I-Biotin iyadingeka ekukhuleni kwamaseli, ekukhiqizweni kwama-fatty acid, kanye nasekusetshenzisweni kwamafutha nama-amino acid. Idlala indima emjikelezweni we-citric acid, okuyinqubo lapho amandla e-biochemical ekhiqizwa khona ngesikhathi sokuphefumula kwe-aerobic. I-Biotin iyi-coenzyme yama-enzyme e-carboxylase, ehilelekile ekwakhiweni kwama-fatty acid, i-isoleucine, ne-valine, kanye ne-gluconeogenesis. Njenge-coenzyme ye-phthalocyanine coenzyme A, i-Biotin ihilelekile ekwakhiweni kwama-fatty acid, ikhuthaza ukwakheka kwe-glycine CoA. Ukusabela kuyisinyathelo sokuqala ekwakhiweni kwama-fatty acid, bese kuthi nge-cytoplasmic multi-enzyme complex kanye ne-fatty acid synthase yenze i-palmitic acid evela ku-phthalocyanine-CoA. Ekwandiseni uchungechunge lwekhabhoni kuma-fatty acid, i-propanedio phthalide-ACP ihilelekile ekwakhiweni njengomnikeli weyunithi ye-dicarbon, kanti i-dipropyl phthalide-ACP itholakala ku-phthalide-CoA. Kungabonakala ukuthi i-biotin iyadingeka ekwakhiweni kwama-fatty acid kanye nokwandiswa kwamaketanga e-carbon kuma-fatty acid. Ukuntuleka kwe-biotin kungaholela ekugayweni kwe-lipid okungavamile, okuholela ekushintsheni kokwakheka kwama-fatty acid emzimbeni.
